Description
Technical field
The utility model is related to a kind of strong and weak electricity separate type cable shaft structure.
Background technology
Cable testing bridge and cable shaft are widely used in the cable laying of distribution system, according to GB50217《Power engineering
Cable design specification》Regulation：" cable laid on the Multilayer bridge frame of the same side, should be by the electric power of voltage class from high to low
Control and signal cable, the order arrangement of communication cable ' from top to bottom ' of cable, forceful electric power to light current." however, in distribution line
End, generally require to exchange the relatively low lower floor's cable of voltage class to upper strata crane span structure（Or need voltage class is higher
Upper strata cable is exchanged to lower floor's crane span structure）, so as to cable laying.Current levels cable replaces mainly to be realized by cable shaft,
Exist as shown in figure 1, this mode can not be realized inside cable shaft between forceful electric power cable and weak-current cable isolation, strong and weak cable
Intersect, weak-current cable, which not only insulate, to be on the hazard, it transmits signal and can be also interfered, and easily becomes the event of cable laying system
Hinder point, therefore it is one the problem of merit attention to realize that layer is changed in the separation between strong and weak electrical cables.
Utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of structure design and close
The strong and weak electricity separate type cable shaft structure of reason, can be achieved isolation when forceful electric power cable and weak-current cable top-bottom cross are changed layer.
The technical scheme in the invention for solving the above technical problem is：A kind of strong and weak electricity separate type cable shaft knot
Structure, including cable shaft and horizontal crane span structure；Horizontal crane span structure is connected with cable shaft, and horizontal crane span structure is many, is separately positioned on electricity
On the side of cable vertical shaft both sides, the horizontal bridge positioned at cable shaft the same side put up it is setting up and down, horizontal crane span structure be provided with cable
Laying area；It is characterized in that：Also include fire barrier and side-wall hole plugging plate；Fire barrier is fixed on cable shaft vertically
Inside, forceful electric power cable area and weak-current cable area will be divided into the horizontal direction inside cable shaft；Connection on cable shaft
The side for having horizontal crane span structure is provided with least two side-wall holes, and these side-wall holes are located at the company of cable shaft and horizontal crane span structure
Meet place, and be divided into by boundary of fire barrier two groups, one group of side-wall hole respectively with forceful electric power cable area and cable laying regional connectivity,
Another group of side-wall hole respectively with weak-current cable area and cable laying regional connectivity.
The utility model also includes cover plate, and cover plate is arranged on cable shaft upper and lower ends.
Fire barrier and side-wall hole plugging plate described in the utility model is made by fire proofing material.
The utility model the utility model compared with prior art, with advantages below and effect：Multi-layer cable can be achieved
Layer is changed in the separation of forceful electric power cable and weak-current cable in crane span structure, with it is simple in construction, be easily installed, cost is low the characteristics of, can apply
In cable laying.
